This is the second generation of the chassis with a single piece bent sheet metal lid. It allows for easier access to components and better weather resistance since there are not longer any cracks in the lid for water and dust to settle into. The chassis is entirely enclosed and can be used in most weather conditions. It is designed for the wheels to be axle mounted and supported by two sealed ball bearings. This moves the payload so that it is entirely supported by the chassis instead of the motor. Each of the four axles are chain driven by a large and powerful IG42 Gear motor via a roller chain to yield a very smooth and slip free mode of operation. This robot is designed for loads greater than 20lbs. For loads greater than 35lbs you need to go with lower gear ratio motors and pneumatic tires. The biggest issue with weight is pivot turns on carpet and grass takes a great deal of torque to skid steer.
This is the chassis and hardware only, for the wheels, motors, etc. see our wheeled robot kits.
The ends of the shafts are exposed on the inside if you wish to mount encoders to them. Or you can select gear motors with encoders on them. There are side access panels that allow easy assembly of the motor and chains and adjustment of the chain tension.
The chassis frame is made of 1/8" thick aircraft grade aluminum. The design uses all laser cut parts with mortise and tenon design for precise alignment and mating of the parts. The covers are tinted acrylic that is also laser cut to match the holes of the mating flanges that are tapped after the laser cutting. A galvanized metal cover for shielding EMF is provided for going over the four motors which are mounted in the center. A middle tray is also provided that mounts on top of the motors for mounting your batteries, camera system, and/or electronics. The chassis is completely welded using TIG and MIG.
Gaskets are also provided for sealing the acrylic covers. All the necessary motor mounting hardware, chains, sprockets, etc. are provided as part of the chassis. The chains provide a 10:15 reduction motor to wheel shaft.
